MATTRESS-FRAME OR BED-BOTTOM.

SPECIFICATION forming part of Letters Patent No. 237,586, dated February 8, 1881. Application filed October 14, 1880. (No model.)

To all whom it may concern:

Be it known that I, FREDERIC A. PALMER, a citizen of the United States, residing in the city, county, and State of New York, haveinvented certain new and useful Improvements in Bed Bottoms; and I do hereby declare that the following. is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and letters of reference marked thereon, in which- Figure 1 is a plan view of my improved bedbottom. Fig. 2 is a side view of the same. Fig. 3 is a vertical longitudinal section in the line :l: of Fig. 1. Fig. 4 is a cross-section in the lineyyof Fig. l; and Fig. 5 is a perspective view of the adj usting-iron employed for stretching the Woven-Wire fabric, or other proper fabric, applied over and upon the bed-bottom frame.

My invention relates to movable frames of wood or metal, made to lit any bedstead, and used for sleepin g and other purposes, on which frame Woven-wire or other suitable fabric is stretched, designed to support the bedding, and to take the place of all slats, spiral-springs, and palliasses.

The object of my invention is' to provide an improved movable frame or mattress, to be used in bedsteads or to be supplied with legs and stand on theiioor) in the place of slats, springs, or other appliances for the support of the bedding. On such frame is securely fastened, by nailing or otherwise, and stretched from end to end, attached or unattached to the sides at will, an elastic sheet or fabric, with the frame so constructed that the necessary tension can be obtained and the fabric held iirmlyin place Without the aid of corner-irons, standards, or their equivalents, and at the same time rendering it impossible for the fabric to materially sag or slacken in the middle.

The following is a full and complete description of my invention, which consists of a wood or metal frame, so made, as shown in the drawings, that the end bars, A and A', rest directly upon the side rails, B B, at right angles, projecting over and extending beyond the same, as represented in Fig. l, on which frame the woven-Wire or other fabric WV is elevated and stretched from end to end in such manner that the fabric completely covers and overhangs the side rails, B, and above the same. One end bar, as at A', of myframe, with the fabric securelynailed or otherwise fastened thereto, is bolted firmly through the side rails, B, as indicated in Figs. l and 2, as near the end of the same as practicable, While the other end bar, A, ofthe frame, With the fabric NV securely fastened to it, is held down to the side rails, B B, by a bolt, o, said bolt passing through a slot, G, in an adjusting-iron, F, which is seated in a rabbet, g, cut in the side rails, as shown, and therein firmly held bya bolt, o', to the corresponding ends of the side rails, B, as represented in Fig. 3.

On the under side of the bar A, near each end thereof, is a groove, g', cut at right angles with said bar, into which groove g' an elevated or raised part, f, of the adjustingiron F fits firmly, thereby rendering the frame stiff, firm, and immovable otherwise the bolt o, passing through the adjusting-iron F and Vend bar, A, would act as a pivot on which the end bar would Work,77 and so cause the frame to be weak and unsteady. This iron F serves three purposes, to wit: [t affords the means of securing tension tothe fabric W bya set-screw, E, inserted in an upright portion, r, of the same, which screw forces the end bar, A, outward, the bolto in the bar sliding during such act in the slot Gr in the iron F. It is also an' intermediate means by which the end bar, A, and side rails, B, of the frame are united; and, lastly, its elevated part f, which ts closely into the groove g' made in the end rail, A, to receive it, keeps the frame firm and stiff, and prevents the frame from Wabbling or working on the bolt o, which passes through the end bar, A.

The side rails, B B, of my frame are cut sloping at their ends, as shown, so that the end bars, when secured to the same, incline backward, thereby drawing the fabric W tightly across and upon the upper side and inner edge of the end bars, and so stiifening and reducing the tendency of the bars to bend under strain, and preventing-them from tipping inward. l

The end bars, AA', of my frame are crowned or cut circular, as at t', being wider in the cen-4 ter of their length than at the ends, and also project beyond the side rails, B,at will. This Ico crowned shape prevents them from bending` inward at their center when under great strain due to tension of the fabric V. rlhe groove g in the end bar, A, is indispensable to keep said bar from working pivotally on the bolt c, which passes through the bar,and the iron F, which unites the bar to the side rails, B B.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A mattress-frame or bed-bottom which comprises in its construction, first, side rails with both ends sloping outwardly, as shown; second, end bars applied upon the sloping portions ot' the side rails and extending beyond the side rails; third, a woven-wire or other fabric, \V, applied upon the end bars and ex tending beyond or overhanging the side rails of the frame; and, fourth, mechanism for holding the end bars in position upon the side rails, and for adjusting one ofthe end bars in order to stretch the woven-wire or other fabric, substantially as described.

2. A side rail, B, rabbeted at one end, as at g, to receive au adjusting-iron, F, and with both ends made sloping on top to compel the end bar to incline outwardly, substantiallY as and for the purpose described.

3. The adjusting-iron F, having an upright portion, i', threaded to admit a set-screw, R, and slotted at G to receive a sliding bolt, c, and having an upward extensiomf, to enter the groove g in the end bar, A, substantially as and for the purpose described.
